纳维泵测试技术在大港油田的应用

The Application of Navi Pump DST Technique in Dagang Oil Field .

纳维泵测试试油周期短 ,排液能力强 ,录取资料全。对高粘度、高密度、地层压力低、易出砂的井 ,可采用纳维泵井下开关井、不加MFE多流测试阀的管串结构。介绍了纳维泵测试技术在大港油田板桥地区浅层勘探中的应用效果 ,并建议在钻井过程中及时采用原钻机纳维泵测试技术 ,以便及早发现油气层。

Drillstem test with a Navi pump requires a short test period, it has strong flowing back capacity and is able to acquire complete data. To the wells with high viscosity, high density, low formation pressure and easy sand production, a string may bedesigned with A Navi pump as a downhole shut-in valve and without Mrs test valve. This paper introduces the applicationresults of Navi pump DST technique in the shallow formation exploration of Banqiao area, Dagang oil field, and it recommendsto utilize Navi pump DST technique timely during drilling operation in other to discover oil and gas formation as soon as possible.
